A. Performance characteristics:

1. The chemical stability and hardness (Rockwell hardness hrc90) of ceramic materials are second only to diamond. Therefore, the valve has high wear resistance, corrosion resistance, erosion resistance, good heat insulation and small thermal expansion;

2. The ball is manufactured by advanced grinding equipment and technology, with high roundness precision and good surface quality. After lapping with the valve seat, good sealing performance can be achieved by using the self lubricity of Zr02 ceramic;

3. The defects of metal hard seal ball valve, such as easy leakage, large torque and non corrosion resistance of sealing surface, are completely changed;

4. Ceramic good wear resistance, so that the valve durable, high reliability, long service life, is titanium alloy valve and Monel valve 2-4 times;

5. It is used in the medium of high hardness particles, or the medium with soft particles but corrosion. The valve has incomparable absolute advantage and is the only valve suitable for this kind of medium at present;

6. Drive mode: manual, pneumatic, electric, hydraulic.

B. Applicable conditions: it is suitable for dedusting system of steel plant and blast furnace gas and desulfurization system of power plant under high wear or strong corrosion conditions.
